    Oase in tank filter

    It will be fine for a planted tank without CO2 injection. If you are going to use CO2 you will probably need more flow. Not necessarily from a bigger filter, - you could add a powerhead for the extra flow.

    90p planted aquarium filtration

    Your canister should provide enough filtration, it is only flow you need to increase, so you could stick with the Sicce if you're happy with it and add a powerhead for extra flow.

  16. sparkyweasel

    Am i calculating actual flow right ?

    The rating is for pumping horizontally. Pumping upwards reduces the flow, sometimes drastically. Some pumps have a graph to show flow against head (height). Also the length of tubing, radius of bends and any connectors will reduce the flow.

    They are thermostatically controlled, so they will only use the amount of electricity needed to keep the tanks at the temperature you set them for. The total running cost will be the same.

    Which External Filter is best?

    I think a lot of Eheim's current problems are down to quality control, - or lack of it. It sems to be a gamble where you could get a really good one, or you might not. It's rather sad, they used to make nothing but good stuff once.

    Are you intending to inject CO2? If so, the 10x rule is a good one. Without injected gas a much lower flow is fine.

    Eheim filter flow ratings?

    Some filters, including most internal ones, are supplied with media. In my experience they still don't manage the flow claimed on the box, even if you take the media out. And with an internal you can take the head out of the equation. And pipe lengths and bends. I've got some very good filters...

    Going filterless?

    Without the filter, perhaps you would have syphoned it out. Then it might cause less algae. If it decomposes in the filter it pollutes the tank water a lot more than if it's in the bin. :)

    Advice Needed

    Lol, great minds type alike. :)
  37. sparkyweasel

    Advice Needed

    A lot depends on whether your are going to inject CO2. If you are, more flow would be better, - not necessarily more filtration, as you can use powerheads or wavemakers to add flow. Without injecting CO2 it's more a question of what you are going to keep in the tank.

    Can i run a rattling canister ?

    Note that it doesn't say Vaseline on the sachet (only in the seller's description). Could be a bit of mistranslation. 'Spezialfett' means special grease. It is a silicon grease, which will not damage rubber. Actual Vaseline® is petroleum-based and does attack (at least some kinds of) rubber.

    Hi Hughesy124, it depends on what you're planning for your tank. If you're going to inject CO2 the general rule is that you need the filter's claimed flow to be 10x tank volume per hour, to ensure good distribution of the CO2. If not, you can go for a less powerful filter, or stick with high...

    Hamburg Matten Filter

    If it stays like that consistently it's not a problem, you can set the thermostat accordingly. You might check whether it just gets hotter behind the foam when the heater is on, and the main tank area gradually warms up to match. You don't want a lot of fluctuation as it's a fry tank.

    Effect of changing pipework diameter

    Eheim states that is for "operational safety", not flow rate. Perhaps they test the seals etc for leaks to a certain pressure, maybe test at 2m so they're confident to recommend 1.8m max.
  74. sparkyweasel

    Effect of changing pipework diameter

    Remember that if your intake and outlet are both submerged in the same tank, the head is zero. If your outlet is above the water surface, the head is the height from the surface to the outlet, everything else levels itself, doesn't use pump power.
